Letters Patent No. 111,819, dated February 14, 1871.

IMPROVEMENT IN FEED-CUTTERS.

The Schedule referred to in these Letters Patent and making cf the same.

We, JOHN (hunny, of Shiloh Hill, and WHITNEY GILBREATH, of Rockwood, both in the county of Randolph and State of Illinois, have invented a certain new and Useful Feed-Gutter, of which the following is a specification.

Nature and Object of the Invention.

as corn-stalks, hay, straw, or sheaf-grain, dry or green.

Description of the Drawing.

The drawing is a perspective view of our improved feed-cutter, a portion of one of the guide-straps being broken away to show one of the friction-wheels upon which the lower knife is carried.

General Description.

A B C D E are the supporting legs, connected by tie-bars F G H I I' J.

K, is the box for reception of the material tolbe cut.

L is a knife attached to a cross-bar, l, above the month of the box.

M is a knife attached to'the upper part of a board or plate, N, having curved slots, 'n n'.

0 O are anti-frction-wheels jonrnaled in the frame and in the guide-straps I) P' ofthe knife-plateL or board N.

Q is a bar connecting the upper part of the guidestraps I l", the. said bar serving to prevent the ends of the feed from heini thrown upward by the pressure of the knife M.

Part of the strap I is shown broken away to exhibit the anti-friction-wheel O', the wheel O being similar to that O', and fulfilling a similar purpose. Its position behind the strap P is shown by dotted lines.

Round pins may take the place of the wheels O O'.

`It is a pitman connecting the knife-plate N with thc crank s of the shaft S.

The shaft S carries a balance-wheel, T, and has a crank, s', which is connected by a pitman, U, to oner The end of the knife nearest to the operator is first raised, and when it is sniiciently pressed against the feed the sliding motion of the knife increases andthe other end commences to rise, so that arocking motion is given to the knife; and it is made to commence cnt ting at one side of the mouth and to eut across to the other side, instead of cutting simultaneously from side to side, as is usual.

In some cutters the knives have a circular or verti -cal mot-ion, and their edges are inclined tothe upper and lower margins of the mouth, so as to commence cutting at one sideand to progress to the other; but these knives receive no rocking motion, and differ in that respect from ours.

The peculiar motion of the lower knife and the association' therewith of 'the upper knife causes the cut to be made in the manner of a draw-shears, and it has been found to cut any feed, from corn-stalks to green oats, with great ease. l

The bar Q is situated outside of the knives, and prevents the ends of the feed from being raised and escaping from the knife, and forcing the latter outward from the mouth of the box.l

The knife M might be made to rise first at the opposite en d to the one described, or the knives may be reversed, the iixed knife being placedbelow and the moving knife above; but the arrangement shown is that preferred by ns.

N o device is shown for moving forward the feed as it is cut, and this maybe done bythe hand, or by any of the well-known appliances therefor, such as a small rake hung to the bo'x and operated by hand.

Claims.

Te claim as our invention- 1. The knife-plate or board N,.having curved slots n n', and carried on two pins or anti-friction-rollers O O', substantially as and for the purpose described.

2. The combination and arrangement of the rock` ing draw-knife M N a n and fixed knife L, substantially as described.

3. The combination and' arrangement of the treadle V, pitman U R, cranks s s', shaft S, balance-wheel T, knives M, and -slotted plate or board N, a n', and L, as described.

In testimony of which invention we have hereunto Set our hands.
